解决更新python版本后，虚拟环境不可用的问题

因为安装xformers，需要额外加装triton，而triton需要的python版本（3.10）高于我当前虚拟环境的版本（3.8），因此博主手动提升了当前虚拟环境的版本：

conda install python=3.10

结果应用该虚拟环境时，始终报如下错误：

(TrainControlNet) F:\XYX\Documents\SpongeCakeInverse\AITools\the 3rd party packages>pip install triton-2.1.0-cp310-cp310-win_amd64.whl

解决方法

1. 进入虚拟环境
2. conda install libffi
